<h2><a href="http://favelets.com/">Favelets</a>
For The Validator</h2>
<div class="intro">
<p>
<a href="http://favelets.com/">Favelets</a> are small snippets of
JavaScript embedded in a Bookmark
<acronym title="Universal Resource Identifier">URL</acronym>
that allow Bookmarks in browsers to do various advanced things.
Popular <a href="http://favelets.com/">Favelets</a> include variants
that prompt the user for a phrase and search the web for that
phrase, or that finds older versions of the currently viewed page in
the <a class="offsite" title="The Internet Archive WayBack Machine"
href="http://www.archive.org/">WayBack Machine</a>.
More Favelets can be found from
<URI:<a href="http://favelets.com/">http://favelets.com/</a>>.
</p>
<p>
<a href="http://favelets.com/">Favelets</a> depend on support for
<code>javascript:</code>
<acronym title="Universal Resource Identifiers">URLs</acronym>
in your browser's Bookmarks feature, and each
<a href="http://favelets.com/">Favelet</a> may depend on
support for a specific part of the JavaScript specification to work
properly. <acronym title="Microsoft Internet Explorer">MSIE</acronym>
versions 5.0 and later, and Mozilla 1.0 and later — including
browsers using the embedded version of Mozilla, such as
Netscape 7.0 — are known to support most
<a href="http://favelets.com/">Favelets</a>.
</p>
<p>
Most browsers that have support for basic JavaScript and
<acronym title="Document Object Model">DOM</acronym> also support
basic <a href="http://favelets.com/">Favelets</a>, but more advanced
<a href="http://favelets.com/">Favelets</a> may require more complete
<acronym title="Document Object Model: Level 1">DOM1</acronym> and
<acronym title="Document Object Model: Level 2">DOM2</acronym>
support. Netscape 4.x is a lost cause in this regard, and with its
poor support for standards in general it is probably better to avoid
it altogether.
</p>

<div>
<dl>
<dt>"<a href="javascript:void(window.location='http://validator.w3.org/check?uri='+escape(window.location))"
title="Validate This Page">Validate <em>This</em> Page</a>"</dt>
<dd>
This is the basic "Validate This Page" <a href="http://favelets.com/">Favelet</a>.
It simply submits the URL for the currently viewed page to the
Validator for processing. Results appear in the same window.
</dd>
<dt>"<a href="javascript:window.open('http://validator.w3.org/check?uri='+escape(window.location));void%200"
title="Validate This Page In New Window">Validate <em>This</em> Page In New Window</a>"</dt>
<dd>
Like the last <a href="http://favelets.com/">Favelet</a>, this also
submits the URL of the current page to the Validator for processing,
but this version will show the results in a new window.
</dd>
<dt>"<a href="javascript:void(q=prompt('Validate Page:',''));if(q)void(window.location='http://validator.w3.org/check?uri='+escape(q))"
title="Validate Page...">Validate Page...</a>"</dt>
<dd>
Puts up a dialog with a text entry field where you can type in the
URL of a page you would like to Validate. The results appear in the
current window.
</dd>
<dt>"<a href="javascript:void(q=prompt('Validate Page:',''));if(q)window.open('http://validator.w3.org/check?uri='+escape(q));void%200"
title="Validate Page In New Window...">Validate Page In New Window...</a>"</dt>
<dd>Same as above but shows results in a new window.</dd>
<dt>"<a href="javascript:_is=document.createElement('iframe');_is.setAttribute('src','http://validator.w3.org/favelets.html#'+window.location.href);_is.setAttribute('height','0');_is.setAttribute('width','0');_is.setAttribute('style','border:0;');document.body.appendChild(_is);void 0"
title="Is This Page Valid?">Is <em>This</em> Page Valid?</a>"</dt>
<dd>
From the Head Of The "JavaScript Juju" Department,
<a href="http://jibbering.com/">Jim Ley</a>, comes this gem.
When invoked, this <a href="http://favelets.com/">Favelet</a> will
submit the
<acronym title="Universal Resource Identifier">URL</acronym>
for the current page to the Validator for processing and pop up
a dialog that shows whether the page is Valid and how many errors
where found in the page. As with all Jim does, this Black Magic is
so deep I'm <em>afraid</em> to ask him how it works.
